Albert Marden, he of the tameness conjecture. If you type in Marden and Mostow Rigidity into Google Scholar you'll see this kind of reference. According to one of them that I scanned, it seems the cite should be to Marden's 1974 Annals paper, but I didn't look at it. —Preceding unsigned comment added by 64.131.160.10 (talk) 11:23, 5 April 2010 (UTC)

An important corollary is that a finite volume hyperbolic n-manifold M for n > 2 has no nontrivial inner automorphisms of π1(M). One can conclude that the group of isometries of M is finite and isomorphic to Out(π1(M)).

I think this is obviously wrong since the inner automorphism group of a group is trivial if and only if the group is abelian. But the fundamental group of a finite-volume hyperbolic manifold is never abelian. —Preceding unsigned comment added by AlreadyDone (talk • contribs) 09:16, 14 April 2010 (UTC)
